LEAF PULVERIZING DEVICE This invention relates to pulverizing devicesand more particularly to a device for pulverizing leaves.

It is therefore the main purpose of this invention to provide a leafpulverizing device which will consist of a truncated pyramid shapedplatform in which the leaves are placed through an opening at the top.

Another object of this invention is to provide a leaf pulverizingdevice, the platform of which has a plurality of recessed openings forpositioning the wheels of a lawn mower placed on the top of theplatform, the lawn mower providing the power for pulverizing the leavesand drawing the leaves upwards into the blades of the lawn mower to bepulverized, after which the pulverized leaves are exited through anopening through the side of the lawn mower so that they will fall in apile.

A further object of this invention is to provide a leaf pulverizingdevice which will prevent having to burn leaves and will produce lesscontamination of air.

Other objects of this invention are to provide a leaf pulverizing devicewhich is simple in design, inexpensive to manufacture, rugged inconstruction, easy to use and efficient in operatlon.

These and other objects will become readily apparent upon a study of thefollowing specifications together with the accompanying drawing wherein:

FIG. I is a side view of the present invention shown in use;

and

FIG. 2 is a top plan view of the device showing the lawn mower removedtherefrom.

According to this invention, a leaf pulverizing device is composed of atruncated pyramid shaped platform 11 of hollow configuration. Platform[I is provided with a top surface 12 which has a plurality of spacedapart openings 13 for receiving the wheels 14 ofa lawn mower 15. Andopenings 16 through surface 12 allows for the leaves 17 within platform11 to be drawn upwards into the blade (not shown) of lawn mower in orderto be pulverized and expelled from lawn mower l5. As the leaves 18 arepulverized they are exited from opening 18 of lawn mower l5 and willpile up alongside platform ll.

A rectangular opening 19 through surface 12 allows for the placement ofleaves 17 into the interior of platform 1].

When the blade (not shown) of lawn mower I5 is of the proper design, itwill create sufficient suction by differential in pressure to raiseleaves 17 upwards through opening 16 in order that they may bepulverized by the lawn mower 15.

If desired, opening 20 of top surface 12 of platform I] may be utilizedby extending exhaust pipe 21 into sleeve 22 which will further agitateleaves 17 so that they will raise upwards and be drawn through opening16 into lawn mower 15.

it shall be noted that the use of the exhaust of pipe 21 is notnecessary when the proper blade is used in lawn mower 15 as the properblade will create sufficient vacuum to raise leaves 17 so that they maybe pulverized by lawn mower l5.

lclaim:

1. A leaf pulverizing device comprising a hollow truncated pyramidshaped platform having in its top side a rectangular intake opening, acircular opening and spaced apart openings placed symmetrically aboutsaid circular opening, a lawn mower having a power driven rotary bladepositioned upon said platform, said blade providing means of creatingsuction within said platform for raising tree leaves from the interiorof said platform into the blade of said lawn mower in order to pulverizethem.

2. The combination according to claim I, wherein said lawn mower isplaced on the top surface of said platform in such a manner as to rotatethe wheels of said lawn mower within the spaced apart openings of saidtop surface of said platform, thus aligning the blade of said lawn mowerwith the opening of circular configuration in order that leayes whenplaced through the rectangular opening through said platform will besucked up into said blade and be pulverized by said blade of said lawnmower.

3. The combination according to claim 2 wherein said lawn mower whenstarted will create a suction by its blade over the circular opening ofsaid platform, said suction creating an upward movement of said leaves,thus the suction drawing said leaves into the blade of said lawn mowerwhereupon the blade will pulverize said leaves and expel said leaves inpulverized form from an opening in the side of said lawn mower.
